10 stars would be more appropriate! We have been in our off grid solar home for 9 years with out a hitch. I had the good fortune to call Tom Duffy as I was designing our home and he took the time to walk me through ALL of the things that would make our solar experience seamless. He is a problem solver and not an order taker, he took the time to understand what we wanted to do and helped us to get there. I shopped hard and then called Tom, in the end we got better equipment for less money. In this day and age I believe you get what you pay for, cheap gear is not the way to go. What we got with The Solar Biz was an amazing amount of value. I have recommended them to friends and they have had the same experience that I have. Such a pleasure to find folks that want to help you, such a pleasure to work with the Duffy’s.

I have been dealing with the Solar Biz for years, and am never surprised by the staff's friendly attitude, helpful demeanor and technical know how. I have spent thousands there over the years, and always get super service no matter if its a small screw, or a new battery bank. They have literally helped me design and maintain my solar system, from the ground up. They've spent hours on the phone with me, walking me through the steps to build a safe, efficient system. Patty, Tom and Barb are the best in the business! They make a great team. If you have a problem, they make it their problem until your happy. Thanks again for the great help over the years guys!

I am an electrical contractor and solar installer and I must say this is an absolutely wonderful company to do business with! The engineers go above and beyond to ensure the best product for years and years of use. I have countless new clients who have had their systems engineered by the solar biz who have been problem free and boast how pleased they where with their choice. Their low prices and wonderful customer service will keep me coming back for many years!

The utmost professional and fast service in the business - BAR NONE!! Look forward, with great enthusiasm to doing business with Solar Biz again soon! Thanks to the entire Solar Biz team for what is obviously a team effort to make my order go so smoothly and quick. I greatly appreciate all the extra effort your company puts into making sure all my needs are met. UTMOST PROFESSIONAL!!!

I have since made 2 more purchases from Solar Biz and have always found the staff extremely helpful, offering expert advice on solar products and installation. Solar biz prices and service are unbeatable. Thumbs up -- Thank you Solar Biz staff.
